T 0 all whom it may concern: Be it known that 1', WILLIAM LINK, a citizen of the United States, residing at Tulsa,

Oklahoma, have invented a certain new and useful Improvement in Diestocks, of wh ch the following is a specification.

My invention relates to die stocks. I

The object of my invention is to provide a die stock with novel oiling means, and which is simple in construction, cheap to manufacture, not liable to "get out of order, which is eilicient in operation, and which is adapted for oiling dies of different diameter. The novel features of my invention are hereinafter fully described and claimed. In the accomp anying drawing, which illustrates the preferred embodiment of my 1nvention,

Figure 1 is a side elevation of my 1mproved die stock.

r Fig. 2. is a plan view of the same; 7 t

Fig.3 is an enlargedlongitudinal section of a part ofthe die stockg Fig. 41 is a 'lorigitudinalsection, further improvements in ,enlarged, of a partof theoil conductor, and

showing in elevation, valve. a

Similar reference characters designate similar parts" inthe difierent views.

1 designates the body of an ordinary revoluble die stock having the usual means for holding a die 2.

The die stock is provided with the usual diametrically opposite handles 3 and 1 disposed radially with respect to the body 1.

The handle 4: comprises a radially disposed tube externally screw-threaded at its ends, the inner end being fitted detachably end be ing provided with an internally threaded collar 6.

The tubular or hollow handle 4: is pro vided with an air inlet and an oil outlet at its outer and inner ends respectively.

Connected with the outlet is an oil conductor comprising the following described parts.

apart of the outlet f externally screw-threaded tube 7, Fig. is fitted ina screw-threaded hole in the socket 5 located axially and radially with respect to the longitudinal center of the handle 4.

fitted the outer end of an externally threaded screw 9, on the inner end of which is fitted a cap 10,-in which is secured the outer end of a right-angled tube 11, which forms the discharge portion of the conduc tor, and which has its outer end disposed in the die 2, as shown in Fig.3.

By radially adjusting the tube 7 and sleeve 8, the discharge tube 11 may be moved radially so as to properly adjust it for oiling dies of different sizes. The'outer end of the tube 7 is preferably extended beyond the be readily gripped, when the handle't is detached from the socket 5, for turning it to its proper position in the socket.

For closing theouter end otthe handle 1, an externally threaded plug 12 is fitted in the threaded outer end of the tube 1. The plug 12 is provided with an air inlet hole 13, which is normally closed by means of a preferably inwardly opening seli closing adapted to bear against the inner side of the plug 12 and provided with a stem 15 which extends through the hole 13 and has-mounted on it a collar 16, against which bears the outer end at a coil spring circles the stem 15, and which has its inner end bearing against the outer side of the plug 12. The spring 17 normally forces the valve 1 1 to the closed position.

For normally closing the outlet of the handle 1 for controlling the flow through the conductor, I provide a preferably self-closing valve .18, which is mounted in the sleeve 8 and is adapted to bear against the inner end of the tube 7 which forms a seat for the said valve.

The valve 18 is provided with an axial stem 19, which extends through the tube 7 and is longitudinally slidable in a screwthreaded plug 20 which is fitted in a screwthreaded hole extending centrally through the plug 12.

A coil spring 21 encircles the stem 19 and bears at its inner end against the outer end of the plug 20, and bears at its outer end against a thumb piece 22, which is secured in the collar 6, within which the thumb piece is reciprocative, to the outer end of the stem 19.

17, which envalve 14 stem 19 and valve 18, so as vThe thumb piece 22'is of When the die stock is turned, in revolving, while cutting a thread, so that the handle 4 is at the top and in the vertical position, the operator may permit oil to flow by gravity from the hollow handle 4, which forms the oil receptacle, through the con" n V g by depressing the thumb piece 22, thereby forcing downwardly ductor and into the die 2,

' the valve for ofoil has been discharged, the thumb piece 22 is relieved of pressure of the operators upon. which-the springs 17 and 21 will respectively force the valves '14 :and 18 to closed position. v

In order that the valve 18 shall not upon striking the outer end of'the tube 9 shut off the flow of oiltherethrough, the tube 9 is provided at its outer end, with one or more 7 notches 23, through which the oil can pass The internalydiameter of the sleeve 8 ;is greater than the larg est diameterof the valve 18, thereby providing w an annular space around the passage of oil. The handle 4 adjacent to the socket 5 is providedwith 'a filling hole which isscrewthreaded and has detachably fitted in it a threaded plug 24.
